V indon Conditioning Cabinets

The Vindon Cabinet with controlled temperature, humidity and BS 950 daylight illumination.

The benefits for use in the textile industry

Vindon Cabinets have helped to solve a significant problem for the textile industry in achieving repeatability in colour matching and dying consistency.

The cabinets overcome problems in preparation of test samples created by changes in environmental conditions – including sunlight, temperature and humidity – which can alter the shading process and create “drift” away from the specified colour standard. By being able to set humidity, light and temperature at specified levels, fabrics can be prepared and tested in controlled conditions. A major benefit in improving quality control procedures.

Used in conjunction with a spectrophotometer, the cabinets provide a vital tool in testing and controlling colour standards where fabrics are manufactured or dyed in bulk.

Whilst the spectrophotometer helps to provide precise colour fingerprints the conditioning cabinets can ensure the same shade standard are met, time after time, at whatever location throughout the world the dyeing process is undertaken.

Humidity

Humidity is created by externally mounted ultrasonic transducers which, on the demand of the digital electronic controller, immediately provides a supply of pre-conditioned moist air to the chamber. This method ensures fast humidity equilibration times and makes it ideal for the speedy conditioning of textile samples.

Temperature

Air circulation is fan assisted to ensure uniformity and accuracy of humidity and temperature throughout the chamber.

Daylight Illumination to BS 950 Part I (D65)

This is created by special fluorescent tubes fitted internally to the door.

Elapsed Hour Timer

This records the time period of usage of the lights to assist in replacement frequency.

Water

The water is supplied from a 10 litre reservoir. The cabinet will use approximately 5 litres of water per day. A re-circulating water filter system ensures removal of particles. Clean deionised laboratory grade 2 water is required for the reservoir to (BS 3978: 1987) or (ISO 3936: 1987).
